Kew Pumping Station sewer relining project

Shape Copy 2 Completed

As part of our ongoing Sewer Relining Program, Melbourne Water has completed works to upgrade and rehabilitate five existing sewer pipelines that run from the Kew Pumping Station under the Eastern Freeway in Kew East. 

Melbourne Water and our delivery partners thank the community, residents and park users for their patience and understanding while we completed these works. 

Achievements to complete the project include:

  • 7,500+ work hours
  • 50+ people working across the project
  • 430 metres of sewer relined
  • 1,200 metres of sewer inspected by camera
  • Zero safety issues occurring on site, ensuring our people went home happy and safe

Our project delivery partners included John Holland, KBR, Interflow, JHL Civil and Quality Site Welding.

About the project

Melbourne Water is committed to enhancing life and liveability across local communities. That’s why we’ve upgraded five rising main sewer pipelines that play a vital role in Melbourne's sewer network – transferring sewage from the Kew Pumping Station to the South East Trunk Sewer and onto the Eastern Treatment Plant.

These sewer lines run under the Eastern Freeway in Kew East, and were built in the early 1970s before the freeway was complete. They consist of three smaller (762mm) pipes and two larger (1143mm) pipes, which help relieve pressure on the sewerage system in Melbourne’s north and inner west – including the ageing North Yarra Sewer pipeline.

Inspections showed the concrete inside to be deteriorating, exposing some of the steel reinforcing and needing repair. The sewer pipelines were relined using a ‘spiral wound-in-place’ methodology. Other works were completed to modify the manhole (SET027) under the Burke Road city-bound on-ramp.

With these essential works now complete, we've helped reduce the risk of cracks, leaks or collapse of sewer lines that run under one of Melbourne’s most important arterial roads. This ensures they will continue playing a key role in the safe and effective transfer of Melbourne’s sewage for decades to come.
